#!/bin/bash
usage ()
{
echo 'usage: ge <commit-ID>'
exit -1
}if [ $# != 1 ]; then usage fi
ME= $(commit-id $1); [ "$ME" = "" ] && usage PARENT=$(parent-id $ME); [ "$PARENT" = "" ] && usage TREE1= $(tree-id $ME); [ "$TREE1" = "" ] && usage TREE2= $(tree-id $PARENT); [ "$TREE2" = "" ] && usage
cat-file commit $ME echo git diff -r $TREE2:$TREE1
